To Preserve Quinces
Ingredients
Directions
Prepare the quinces
Wash and wipe the quinces.
Peel and core them using a tin corer or a strong fork.
Cut the quinces into quarters or round slices about ¾ inch thick. Remove any blemishes.
Make the syrup
Place the parings, cores, and seeds in a preserving kettle. Cover with cold water and boil for 1 hour, keeping it covered.
Add 1 pound of sugar per pint of liquid and dissolve it over heat. Bring the mixture to a boil and skim off the scum.
Cook and preserve
Add the quinces. Boil them until they are red, tender, and clear, but not breaking, keeping the kettle covered.
Add a little cochineal sifted through muslin to enhance color.
Remove the quinces and spread them on large dishes to cool.
Boil the syrup again until it resembles fine jelly. Pour the hot syrup over the quinces.
Wait until cooled, then seal the jars with brandy paper.

What each ingredient does
- Quinces
- Provide the fruit that softens and turns red and tender during long simmering.
- Loaf sugar
- Sweetens the fruit and, boiled into syrup, helps it set into a clear, jelly-like coating.
- Cold hard water
- Forms the base of the syrup and, with the parings and cores, extracts pectin for setting.
The step that matters
Boil the quinces until tender but not breaking. Quinces are firm and need long, gentle simmering in covered syrup to soften and turn clear. Boiling too hard or too long breaks the fruit apart and makes it mushy.
